- Summary
- Elliptic's verify function omits uniqueness validation
- Details
-
The Elliptic package 6.5.5 for Node.js for EDDSA implementation does not perform the required check if the signature proof(s) is within the bounds of the order n of the base point of the elliptic curve, leading to signature malleability. Namely, the
verifyfunction inlib/elliptic/eddsa/index.jsomitssig.S().gte(sig.eddsa.curve.n) || sig.S().isNeg()validation.This vulnerability could have a security-relevant impact if an application relies on the uniqueness of a signature.
